<PRE><B>Question 118965</B>
X/3+3/4
3X/4-3/5 NOW MULTIPLY 
-----------------------------
(X/3)(3X/4)+(3/4)(3X/4)-(X/3)(3/5)-(3/4)(3/5)
X^2/4+9X/16-X/5-9/20
X^2/4+[(5*9X-16X)/16*5]-9/20
X^2/4+[(45X-16X)/80]-9/20
X^2/4+25X/80-9/20
[20X^2+25X-36)/80 ANSWER.
THIS EQUATION (20X^2+25X-36) IF REDUCED, NEEDS THE QUADRATIC EQUATION:
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
